CHUTE.

Specification of Letters Patent.

Patented Oct. 31, 1911.

Application filed June 22,1910. Serial No. 568,342.

To all whom it may concern Be it known that I, CHARLES S. FARRER, a citizen of the United States, residing at Dunmore. in the county of Lackawanna and State of Pennsylvania, have invented certain new and useful Improvements in:

Chutes, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to improvements in chutes for slate and coal picking machines.

The principal object of my invention is to provide a simple and practical chute mechanism for slate and coal picking machines, in which the coal will be caused to travel in a zig zag course down the discharge and prevent it from dropping from pan to pan and being broken up.

Another object of the invention is to provide a simple and practical coal discharge chute which will be well adapted for use in connection with my improved coal and slate picking machine set forth in Patent No. 957,320, granted. May 10th, 1910, and any analogous machines.

With the above and other objects in view, the invention consists of the novel features of construction and the combination and arrangement of parts hereinafter fully described and claimed and illustrated in the accompanying drawings in which Figure 1 is a plan view of a double coal discharge chute adapted for use on a dou ble picking machine. Fig. 2 is a side elevation of the same. Fig. 8 is a detail vertical longitudinal section, parts of the picking mechanism being conventionally illustrated. Figs. 4, 5 and 6 are detail views of parts. Fig. 7 is a detail plan view of a single chute especially adapted for use in connection with my coal and slate picking machine set forth in Patent No. 957 ,320. Fig. 8 is a side view of the parts shown in Fig. 7 and Figs. 9 to 14 inclusive are detail views of parts.

Referring more particularly to Figs. 1 to ,6 inclusive, of the drawings, 1 denotes suitably connected channel bars forming the side beams of a supporting frame which is inclined downwardly and preferably mounted on a suitable pivot bearing 2, carried by a stationary support 3, whereby the inclination of the main frame 1, may be varied to change the grade of the picking chute mechanlsms.

Any suitable means may be provided for adjusting and fastening the frame 1. Hising from the channeled side bars of the main frame are upright plates 4, which latter are arranged at intervals and are united by upper side bars 5. These parts constit-ute the principal portions of the main frame 1, within which the picking mechanisms and my improved coal discharge chute mechanism are mounted.

In order to render the construction and operation of my chute mechanism clear, I will briefly describe the picking mechanism which latter is quite similar to the mechanism set forth in my above noted patent. There are several groups of picking mechanisms in the frame, and each one comprises spaced chutes 6, 7 between which is arranged an oscillatory feed member 8, and at the lower end of the lower chute 7, is arranged an adjustably mounted retarding member or surface 9, the latter consisting preferably of a piece of stone, emery or like material, which will check the downward movement of the fiat pieces of slate without materially retarding the movement of the coal. The material as it passes ofl of the retarding surface 9, is separated by an adjustably mounted separating member or knife 10, the coal passing above the latter and on to a plate, while the slate drops on to the chute or plate 6 of the next lower group of separating mechanisms. The parts which I have described constitute a single group of separating mechanism, and this group is repeated or duplicated on each side of the machine in the double machine, and it is also repeated four times lengthwise of the machine in the four drop double picker which I have illustrated. The two lower groups of separating mechanism however, are slightly different from the two upper groups in each of the two longitudinal se ries of groups, the difference consisting in providing a stop plate 11, in the space between the retarding surface 9 and the separating lmife or member 10, whereby the mass of material passing over the retarding surface will be separated into three sections, the coal passing on to the plate above the separating knife 10, mixed coal and slate passing over the stop 11 and on to the chute or plate 6 of the next lower group of mechanism, and the major -portion of the slate dropping in front of the stop 11, and on to a slate chute 12 arranged in the lower portion of the main frame. The coal receiving plates of the four groups of separating mechanisms are designated 18, 14, 15, 16, and the first three of these plates, that is those numbered 13, 14 and 15, deposit coal on to my improved Zig zag coal discharge chute which latter is adapted to conduct the coal from the upper to the lower portion of the machine without causing it to drop from one pan to another, and thereby breaking it into fine particles.

In the double machine the coal from the two plates 13 of the transversely alined uppermost separating mechanisms passes on to two V-shaped chute pans 17, the lower and smaller ends of which are connected to two downwardly and inwardly converging chute pans 18. The last mentioned pans 18 have their lower ends connected to two similar chute pans 19, the latter however, are longer and arranged in downwardly and outwardly diverging relation, the converging ends of all four of the pans 18, 19 being united by substantially right angular connecting plates 20, each of which have upstanding abutting inner portions or flanges 21, united by rivets or other fastenings and laterally projecting base portions 23, to which are riveted or otherwise secured at 24, the ends of the four pans 18, 19. The lower ends of the pans or chutes 19 discharge upon the outer portions of a single discharge pan or chute 25, which may be of any suit-able shape and which may lead to any point of discharge. The coal from the two plates 14, passes on to two v shaped chutes or pans 26 which are similar to pans 17, and which have their smaller lower ends communicating with and connected to the upper ends of two short inwardly and downwardly converging straight pans 27. The lower ends of the latter are connected by plates 28, similar to plates 20, to two longer downwardly and outward diverging chute pans 29, which latter also discharge on the chute or pan 25. The coal from the two plates 15, passes on to two V-shaped pans or chutes 30, which are similar to the pans 17, 26, and the lower ends of which are connected to two straight downwardlv and inwardly converging pans 31, which latter discharge on to the central portion of the chute or pan 25. Both the V-shaped and the straight chute pans above mentioned have upstanding side flanges as clearly illustrated in the drawings, to prevent the coal from passing off of them, and said chutes or pans are suitably' supported on cross bars 32, and by means of upright brackets or supports 33. Owing to this peculiar construction and arrangement of chute pans, it will be seen that the coal will be conveyed from the upper portion of the machine to the lower portions of the same, without dropping it from one pan to the other, and thereby breaking it up, but on the contrary it will have a continuous zig zag passage from the upper to the lower portion of the machine, and will be caused to descend gradually or without excessive speed.

The coal on the two plates 16, is preferably received in two V-shaped chute pans 34, which are similar to the other V-shaped pans, and which discharge into a single dis charge pan 35.

In Figs. 7 to 14 inclusive, of the drawings, I have shown a single coal discharge chute especially adapted for the single picking machine set forth in my Patent No. 957,320. This machine is a three drop picker, and the main frame comprises channeled side beams 1 which are suitably connected and between which are arranged three groups of picking mechanisms similar to those above described. The coal discharge from the uppermost group of picking mechanism passes on to a chute or plate S having a portion of its lower edge arranged at an angle, and carrying an upwardly curved deflectingvplate 54. The latter serves to direct the coal laterally across the plate or chute 8 to one side of the machine, and on to a laterally curved receiving chute consisting of three connected chute pans 55, 56, 57, whereby the coal will be directed laterally across the machine in an opposite direction and its downward movement thereby retarded. The lowermost pan 57 is connected by a straight longitudinally extending pan 58 to the enlarged lower portion of a pan 59, which latter has its reduced upper portion connected to the central or intermediate portion of a chute or pan 8, adapted to receive the coal from the second group of separating mechanism. This pan 8", has the side portions of its lower edge inclined and carrying upwardly curved deflecting plates 60, 61, which serve to direct the coal on to the reduced upper portion of the pan 59. This pan 59 may be extended and connected by a laterally curved or deflected chute to a main discharge chute, (not illustrated) which latter also receives the coal from the plate or chute 8 of the third group of separating mechanism.

From the foregoing it will be seen that my improved construction and arrangement of coal discharge chutes or pans, will effectively prevent the breakage of coal since it will prevent the coal from falling from one pan to another, and will cause the coal to descend gradually in a zig zag or circuitous course instead of allowing it to pass straight down through all. of the chutes or pans, without being checked or retarded as in the coal discharge chutes now generally used.

I claim:

1. The combination of a supporting frame and a series of coal receiving plates, of a main discharge chute and a series of chute pans having their lower ends communicating with said main discharge chute, and their upper ends communicating with said coal receiving plates, the intermediate portions of said chute pans having laterally extending or deflected portions whereby the coal will take a zig zag course.

2. The combination of a supporting frame, a lower coal discharge chute, a pair of transversely alined coal receiving pans,

10 the latter being V-shaped, a pair of downwardly and inwardly converging straight pans having their upper ends communicating with said V-shaped pans, a pair of downwardly and outwardly diverging pans having their lower ends communicating with said coal discharge chute, and a pair of angular connecting plates having united upright portions, and laterally projecting base portions united to the converging ends of the two pairs of straight pans.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
